Low Friction Rolling Element Bearings
Oct 12, 2010· This means that the new cylindrical roller bearings can operate with a much higher ratio of the axial load to the radial load. The ratio that is achievable is 0.6 i.e. a permissible axial load that is 60 per cent of the radial load. Conventional cylindrical roller bearings normally withstand a maximum value of only 40 per cent of the radial load.

What do you know about Cylindrical Roller Bearings
Jan 29, 2015· Rolling element bearings are perhaps the most common form of bearing and operate by carrying a load by placing rolling elements, such as balls or rollers, in between two rings, known as races. A common type of rolling bearing is the cylindrical roller bearing, which, as their name implies, uses cylinders to reduce friction between moving parts.

The friction moments in turn give rise to roller skewing which increases roller-raceway loading affecting bearing friction heat generation and fatigue endurance.
Cylindrical Roller Bearings Selection Guide: Types
Cylindrical roller bearings have high radial-load capacity and moderate thrust loads. They contain rollers which are cylindrically-shaped, but are not true cylinders. Instead, these rollers are crowned or end-relieved to reduce stress concentrations. This geometry results in low friction and allows for high-speed appliions.
